Dangane da kwatancen samarwar mu na ainihi, tsarin ciyar da zaren spheroidizing yana da fa'idodi da yawa akan tsarin spheroidizing na hanyar bugun.

• Inganta yanayin samar da abubuwa a kan-site. Lokacin da wakilin da ke warkarwa ya yi aiki da narkakken baƙin ƙarfe, ana samun hayaƙi mai yawa da haske mai ƙarfi, wanda ke sa yanayin aiki a wurin ya yi muni; lokacin da ake amfani da hanyar ciyar da waya don warkarwa, tashar sarrafawa Akwai murfin rufe jakar spheroidization, kuma murfin yana da alaƙa da tsarin cire ƙura na tashar sarrafawa, ta yadda tsarin kawar da ƙura ke sarrafa hayaƙin na sakin kai tsaye a cikin bitar.
• An rage adadin abin da aka kara da shi, kuma an rage farashin samarwa. Bayan lissafi, sarrafa 1t na narkar da hanyar ciyar da baƙin ƙarfe na iya adana kusan yuan 78 a cikin kayan albarkatun ƙasa fiye da hanyar motsawa. Dangane da ikon samarwa na shekara -shekara na tan 10,000 na ductile iron axle gidaje na masana'antar mu, ceton shekara -shekara shine Kudin shine yuan 780,000 kuma fa'idodin suna da yawa.
• Gane aikin sarrafa kansa da rage ƙarfin aikin ma'aikata. Lokacin da ake aiwatar da tsarin wariyar launin fata, shirye -shiryen farko na ma'aikata yana da wahala, gami da auna ma'aunin spheroidizing da inoculant, ƙara wakili da inoculant a cikin jaka, kuma ana buƙatar Tamping da rufe ayyukan; ana ƙara adadin adadin spheroidizing da inoculating na hanyar ciyar da zaren ta atomatik ta cikin majalisar kulawa, wanda ke rage yawan aiki.
• Ingancin spheroidization tabbatacce ne kuma tasirin spheroidization ya fi kyau. Dangane da kididdiga, tun lokacin amfani da tsarin ciyar da zare a cikin 2013, ƙimar wucewar spheroidization ya wuce 99.5 %, yayin da ƙimar wucewa ta tsarin aikin spheroidization shine 95. %kawai.

5. Yadda za a zaɓi madaidaitan sigogi na ciyar da zaren spheroidization

A cikin samarwa na ainihi, yadda ake zaɓar sigogi na tsarin ciyar da waya yana buƙatar takamaiman adadin gwaje -gwaje don tabbatarwa. Mun yi sauye -sauye da yawa na tsari daga farkon ƙungiyar gwajin zuwa samar da taro na yau da kullun. Na gaba zai raba abubuwan da muke da shi tare da abokan aiki.

Lokacin da kuka ji sautin amsa "boom", duba tsawon ciyarwar nan da nan. Idan wannan tsayin yana daidai da tsayin ƙarfe mai narka, saurin ya dace. Bayan tabbaci, mun zaɓi saurin ciyarwar na 30m/min.
• Zaɓin adadin ciyarwar zare Adadin ciyarwar zaren da ya dace shine ciyar da mafi ƙarancin zaren da aka ƙera ƙarƙashin tsarin tabbatar da tasirin spheroidization. Ya kamata a ƙaddara adadin ciyarwar waya gwargwadon ƙarar sarrafa baƙin ƙarfe mai narkarwa, zafin zafin aiki, da abun cikin sulfur na narkakken baƙin ƙarfe. Dangane da ainihin narkakken abun cikin sulfur baƙin ƙarfe da buƙatun aiwatar da samfur, haɗe tare da tabbatar da gwaji, a ƙarƙashin yanayin tabbatar da abin da ya rage na magnesium, tsawon layin spheroidizing shine 39-46m, kuma tsawon layin inoculation shine 32m.
• Zaɓin zafin zafin aiki Ya kamata a rage zafin aiki gwargwadon iko ƙarƙashin tabbataccen zafin zazzabin. Ƙananan zafin zafin sarrafawa, mafi girman yawan sha na magnesium da ƙarancin yawan amfani da waya mai cored. Dangane da gwajin gwaji na ainihi, lokacin daga farkon maganin warkarwa zuwa farkon zubarwa shine mintuna 4 zuwa 5, lokacin da zazzabin ya sauka daga 40 zuwa 50 ° C, kuma lokacin amsawar spheroidizing shine sakan 80 zuwa 90. Tun lokacin da ake buƙatar jujjuya tsarin juyi, muna saita zafin zafin aiki a 1410 ～ 1450 ℃, ana ɗaukar iyakar babba lokacin da zafin ɗakin ya yi ƙasa da 5 ℃, kuma ƙaramin iyaka lokacin da zafin dakin ya fi 25 ℃.
• Zaɓin abin da ya rage na magnesium a cikin baƙin ƙarfe bayan magani. Yakamata a keɓe abun cikin magnesium na wani adadin abun cikin magnesium gwargwadon halayen simintin kanta. Da farko, mun sarrafa abin da ya rage na magnesium zuwa 0.03% zuwa 0.06%, amma bayan tabbataccen samarwa, ya fi dacewa a sarrafa abubuwan magnesium da suka rage zuwa 0.05% zuwa 0.06%, saboda mun gano lokacin da ragowar magnesium ya yi ƙasa da 0.04%, ginshiƙan sa Zagaye na ƙwallon ya ɗan yi muni. Lokacin da ya fi 0.07%, ciminti yana da saukin bayyana, kuma ƙanƙantar da baƙin ƙarfe ya zama babba.
• Magance matsalar taɓarɓarewar waya yayin amfani Abun damuwar waya zai faru yayin isar da wayar da aka ƙera, wanda zai sa a fasa dukan fakitin baƙin ƙarfe. Don wannan, mun ɗauki matakai masu zuwa: ɗaya shine shigar da zobe na ƙarfe a sama da murfin waya, kamar yadda aka nuna a cikin Hoto na 5, wanda zai iya rage lanƙwasa babban waya kuma ya sa ya shiga cikin tsarin jagora cikin sauƙi; na biyu shine a haɗa murfin biyu Lokacin walda, bayan walda, goge manyan bumps don hana waya ta yi tsami yayin aiwatar da isar; na uku, ka guji lanƙwasawar diamita ƙasa da 1m a cikin bututun isar da hanya ko hanyar da keɓaɓɓen waya don hana waƙaƙƙen wayoyin da ke ɗauke da Foda ko ɓarna a yayin aiwatarwa
